In One Less God Than You, John DeRosa dismantles 20 common atheist arguments, exposing their logical flaws and providing clear, effective responses. From claims that religion causes war to accusations that belief in God is as irrational as belief in Santa Claus, DeRosa equips Christians with reasoned defenses against skepticism. Rather than ignoring or fearing these challenges, the book encourages believers to engage thoughtfully, strengthening both their faith and their ability to evangelize. With atheism more vocal than ever, One Less God Than You serves as a practical guide for responding with confidence and truth.
